Stainless Steel 321 Round Bars are a popular choice in various industries due to their exceptional resistance to high-temperature environments, corrosion, and oxidation. These round bars are made from Stainless Steel 321, a modified version of the 304 stainless steel alloy with added titanium content. This modification enhances its high-temperature performance and makes it suitable for a wide range of applications.

Composition and Properties: Stainless Steel 321 is an austenitic stainless steel alloy, primarily composed of chromium and nickel, with the addition of titanium. The titanium stabilizes the alloy against carbide precipitation during welding and high-temperature exposure. This makes Stainless Steel 321 Round Bars particularly well-suited for applications in elevated temperature environments.

High-Temperature Resistance: One of the most notable features of Stainless Steel 321 Round Bars is their exceptional resistance to high temperatures. They retain their strength and structural integrity at temperatures up to 900°C (1652°F). This makes them ideal for applications in industries such as aerospace, power generation, and furnace manufacturing, where exposure to extreme heat is common.

Corrosion Resistance: Stainless Steel 321 also offers good resistance to corrosion and oxidation, similar to Stainless Steel 304. This property is valuable in applications where the material will be exposed to aggressive chemical environments or in outdoor conditions where it may encounter moisture and corrosive elements.

Weldability and Fabrication: Stainless Steel 321 Round Bars are easy to weld and fabricate, making them suitable for a variety of manufacturing processes. Their ability to withstand high temperatures without losing their structural integrity is particularly advantageous for welding applications.
